Whitehead Reservoir Sediment Use

The DaLing River is a river of much bedload . The average of the loss sand can reach 21434.3 thousandston, and the ratio is 18.08 Kg/m3. To this day, the ratio of sandiness by measuring in the biggest broken surface is 172 Kg/m3.The Baishi reservoir lies in the city named Beipiao which in the middle reaches of the DaLing River in Liaoning Province, The income of the reservoir from the trunk stream is 11457 thousandston ,and from the branch of the river is 1160 thousandston. Letterpress starting with the former of the experiment for bedload. Firstly, we account for the former made and the sand selected are reasonable by experiments . Then we develop the first project carrying the experiment for filling up of 30 years. Contrasted with the count, the results have no difference, We carried two experiments under different water levers by the actually facts If engineering work in early days. By the result, we know that the gross of fill up have no difference. However contrast with the two projects. The gross for fill up of project two is losing. Look from the vertical section plane, project two have not the delta conformation of fill up. Project one lost the effectual contains of reservoir. In opposition , project two lost the dead contains .During the experiment of the local former in front of the dam ,the quantity of the sandiness out the reservoir appears that lot of sandiness passed the bottom hole and little passed the electricity plant and the water gap. This is a distributing trend. All that account for that the project have quite obviously advantage. Form the experiment of different density stream, the stream come into being is quit possibly .Can the sandiness move to the dam and expel from the reservoir suppend on some complications . So as the enter point of the stream, the income of the reservoir, the time of the flood peak lasted, the quantity of sandiness income and the strobe of the darn. We must do some work to forecast and watch the different density stream. By experiments, we made out that it is important for us to reduce the water lever in work of the river belongs lots of sandiness.
